People who live to be over 100 years old often owe their extraordinary longevity to a combination of protective genes and healthy habits. Researchers estimate that up to 50% of a person’s ability to reach extreme old age is due to genetics, but lifestyle factors such as eating a plant-forward diet, staying physically active through regular natural exercise, and maintaining strong social relationships also play an important role. Although scientists have identified immune system characteristics unique to many centenarians, the metabolic changes that accompany healthy aging are still unclear. A new study from Boston University’s Chobanian and Avedisyan School of…

A shift away from organized religion appears to be associated with lower birth rates in modern societies, according to new research. An analysis of decades of population data in Finland finds that declines in state church membership are associated with a continued trend in couples having fewer children. The study was published in the journal Social Science Research. Fertility rates in many high-income countries have fallen to historic lows in recent years. In Finland, the setting for this particular analysis, the total fertility rate fell by 30% between 2010 and 2023. Total fertility rate is a demographic measure that estimates…

Artificial intelligence models can now generate answers to political debates that everyday people find more authentic and relevant than the actual answers given by real-world politicians. This provides evidence that modern technology can easily be used to imitate public figures and spread misinformation that voters easily believe. These findings were published in the journal pro swan. Recent advances in artificial intelligence have led to systems that can generate highly realistic text. Programs such as GPT, Claude, and Gemini fall into the broad category of generative AI. This means that it is a software system designed to create new content based…

UCLA researchers have identified hidden weaknesses in some of the most aggressive and difficult-to-treat cancers, raising hopes for new ways to attack tumors that have resisted treatment for decades. Small cell neuroendocrine cancer can occur in the lungs, prostate, and ovaries. These fast-growing tumors tend to metastasize early and remain among the most difficult cancers to treat. A key feature of these cancers is the deletion of a gene called RB. Under normal conditions, RB helps control cell proliferation. When the gene is missing, cancer cells grow rapidly and become resistant to many targeted therapies. Now, a new study has…

People with migraine experience a reduction in the complexity of their innate brain activity, resulting in their neural networks being unable to adapt to everyday stimuli. A recent study published in the journal NeuroImage suggests that an active migraine attack temporarily shakes the brain back into a more flexible state. This momentary increase in neural unpredictability provides a new perspective on how recurring headaches alter the brain’s internal rhythms. Majid Saberi, a researcher at the University of Michigan School of Dentistry, led the study with Alexandre F. DaSilva and his team. They wanted to investigate how the internal dynamics of…

Recent research published in journals Royal Society Open Science It suggests that a common method used to measure how sensitive people are to internal signals may not actually be linked to mental health conditions such as anxiety and depression. The findings challenge previous assumptions and provide evidence that a widely used heart rate measurement task may not be an effective tool for psychological research. The researchers recommend that future studies rely on other methods of measuring internal consciousness. Interoception is the nervous system’s ability to perceive and process information from within the body. This complex bodily function includes everyday sensations…

A large survey of American adults shows that while the majority supports democratic values, millions of individuals hold views sympathetic to authoritarianism and the government’s use of domestic force. While the individual willingness to engage in political violence remains low among the population, these alternative political preferences are creating a social climate that may encourage democratic backsliding. The study results were published in the journal Injury Epidemiology. Over the past decade, social scientists and policy experts have expressed growing concerns about the health of American democracy. Recent events have been marked by intense political polarization, civil unrest, and changes in…

Recent research published in molecular psychiatry There is evidence that experiencing abuse at various stages in childhood and adolescence changes how the brain processes emotions in adulthood. This study suggests that the particular age at which trauma occurs tends to determine which emotional processing areas of the brain become overactive later in life. These findings provide insight into why childhood maltreatment increases the risk of mental health disorders such as depression and post-traumatic stress disorder (PTSD). The brain relies on a network of highly interconnected structures to interpret and respond to the social world. The two main regions involved in…

An evidence-based analysis of scientific gaps in the 2025-2030 dietary guidelines, focusing on protein, fats, ultraprocessed foods, and integrations with GLP-1 therapies for improved metabolic outcomes.

To commemorate the United States’ 250th anniversary, NASA has released four spectacular images of deep space from the Chandra X-ray Observatory. Each image is rendered in patriotic shades of red, white, and blue. In addition to images, the station also announced three new sonifications that convert stargazing into sound, offering another way to experience the universe.This collection combines data from Chandra with observations from other telescopes to showcase some of the universe’s most remarkable objects, from the remains of exploding stars to distant galaxy clusters filled with evidence of dark matter.Cassiopeia A reveals the aftermath of a stellar explosionThe first…
